CALIBRATION LABORATORY

Goniophotometers for calibration purpose

Goniophotometer for integration of luminous flux via angular resolved measurement of illuminance using CIE (C,γ) coordinate system.

• Goniophotometer for Luminous Flux Integration and Average Colour LMT GO-FI
• Goniophotometer with Flux Integrator LMT GO-V 1920

Integrating Spheres

Measurement of luminous flux or chromaticity coordinates for calibration purposes.

• Integrating Sphere LMT UL 1000
• Integrating Sphere LMT UL 1650

Photocurrent Meters

Photocurrent meter with highest accuracy for measurement of photocurrent generated by photoelectric detectors (photoelements, photomultipliers, etc.).

Photocurrent meters are extremely valuable in calibration laboratories for traceability of photometric units within the SI system.

• Photocurrent Meter LMT I 520
• Photocurrent Meter LMT I 1000
• Photocurrent Meter LMT I 1600

Spectroradiometers for Automotive Lighting

Application tailored spectroradiometers are required for specific radiometric measurements in automotive lighting, for instance UV and red content

• Spectroradiometric measurement system LMT SM 8000-GO
• Spectroradiometer LMT SM A150
• Spectroradiometric measurement system SM 8000-UL

Luminance Meters

Luminance Meters (spot photometers) determine luminance of light emitting surfaces and are very useful to transfer luminance between calibration standards.

• Luminance Meter LMT L 1000
